Why do I get two red dots on the display, regardless of wether I have a trailer connected or not. I’ve hooked it up to a number of different trailers with the same result

Two red dots on the display of the Primus part # TK90160 indicate that the controller is on but a trailer is not detected. Since you are seeing that with multiple trailers connected you most likely have corrosion or dirt built up on the brake output pin of your 7-way which is preventing the controller from being able to recognize a trailer. This is a very common issue and cleaning the pins like mentioned almost always solves the problem. I also attached a help article on troubleshooting brake controllers for you to check out as well.
